Drive shaft dust proof cover for universal joint is located at around automobile driving axle, is automobile driving system for protecting shaft coupling
Cage shield, for storing lubricating grease, and avoids dust, sandstone, water, salt etc. from entering lubricating system, is the important component of automobile
One of, to be resistant to the service condition of extreme abrasion caused by the mud and dirt on road, it is also necessary in extreme temperature
Under the conditions of keep the flexibility of height, taken a sudden turn with adapting to the wide-angle that automobile may occur.
Currently, when being connected with drive shaft telescopic end, coordinate usually using connector sleeve with dust cover makes CVJ dust covers
With being fixed, complex process is inconvenient for use.
The content of the invention
For above-mentioned technical problem existing in the prior art, the present invention provides a kind of injection of new polyester elastomer to be blow molded
Integral dust cover.
To achieve the object of the present invention, the present invention provides a kind of new polyester elastomer to be molded the integral dust cover of blowing,
Including sequentially connected small oral area, Wave crest and wave trough portion and big oral area, the big mouth inner wall is provided with the first circular fin,
Two circular fins, the small oral area madial wall are provided with the 3rd circular fin, on the outer wall of the small oral area and big oral area
The limiting slot being connected with fixing piece is provided with, the first concave part, plane that interval is uniformly arranged are provided with the inside of the big oral area
Portion, the second concave part and arc convex portion, the first concave part, the second concave part structure are consistent, are including radius successively
The first segmental arc, planar section and the radius of R5.25mm is the second segmental arc of R5.25mm, and the radius in arc convex portion is
R30.25mm。
Wherein, the shaping length of the dust cover is 107.5mm, the outside diameter of the big oral area for φ 84.53mm ±
0.3mm, the internal diameter of small oral area is 25.5 ± 0.2mm of φ.
Compared with prior art, beneficial effects of the present invention are, without using extra connector sleeve when use, directly
Big oral area can be fixed, simplify processing technology, and it is easy to use, easy to industrially promotion and application.
